Uniaxial model for gas-loaded variable conductance heat pipe performance in the inertial flow regime

A uniaxial model for the thermal performance of a variable conductance heat pipe (VCHP) has been developed at NLR. The model, so far, accounts for diffusion at the vapour/gas interface as well as for inertia! effects of the moving vapour, Calculations performed have shown that the diffusion effects are of minor importance in comparison with the...

Uniaxial model for a gas loaded variable conductance heat pipe

A new uniaxial model for a gas loaded variable conductance heat pipe (VCHP) is developed. This model takes into account the diffusion at the vapour-gas interface as well as the inertial effects of the moving vapour. Only steady-state conditions are considered. The generally accepted Edwards /Marcus model will be shown to be a first order...
